Overview

This reference design, an 8-channel analog front end (AFE), is demonstrated using two AFE7444 4-channel RF transceivers and a LMK04828-LMX2594 based clocking subsystem which can enable designs to scale to 16 or more channels. Each AFE channel consists of a 14-bit, 9-GSPS DAC and a 3-GSPS ADC that is synchronized to less than 10ps skew with > 75-dB dynamic range at 2.6 GHz.

Features
  • High density, scalable 8-channel RF sampling analog frontend with single FMC interface
  • System clock skew less than 5 psec across devices
  • Clock phase adjustment with 0.5 psec step resolution
  • Low noise clock generation for 14-bit analog frontend performance
  • Digital function (NCO, DDC and so forth) synchronization across multiple transceivers
